Definitions

  • the invention relates to information ID-cards and may be used for cashless payments, e.g., in credit bank operations, in stores, in public transport, etc.
  • a pay card comprising a housing, a microprocessor device, elements of features of a pay system and an issuing bank, protection and personalization
  • the housing of the said pay card is made of a precious or rare metal
  • the said elements of the features of a pay system and an issuing bank, protection and personalization being made of precious and/or semi-precious stones (RU, C1, 2244634).
  • the known device uses gold, and/or platinum, and/or silver as the precious metal.
  • Brilliants, and/or sapphires, and or emeralds, and/or similar stones are used as precious stones.
  • Nephrite, and/or lazurite, and/or chalcedony, and/or stones similar to them are used as semi-precious stones.
  • the elements of the features relating to a pay system and an issuing bank, protection and personalization may be made engraved, and/or inlaid, and/or threaded, and/or electroformed.
  • a limitation of this device is high consumption of precious metals which the pay card housing is made of. Moreover, information for this card may not be entered and read out remotely, since no means are provided for this operation; and if this very design is used, such means may not be implemented without altering International Standards ISO 7816, ISO 1443.
  • This device may not employ the modern technology of NFC (Near Field Communication), that is, the technology of short-range RF wireless communication that enables data exchanges between devices being at a distance of about 10 centimeters (app. 4 inches).
  • NFC Near Field Communication
  • a NFC device may communicate with existing smart-cards, readers according to ISO Standard 1443 and with other NFC devices, and, thus, is compatible to the existing infrastructure of contactless cards already used in public transport and pay systems.
  • the least consumption of a precious metal is realized in a pay card that comprises a foil layer, a first layer and a second layer, which are laminated, the foil layer being secured between the first layer and the outer second layer.
  • the device further comprises a plastic sheet, a magnetic strip, an adhesive layer, and an insert that has a thickness greater than that of the foil layer and is made of the same material as the foil layer, and a decorative element that is secured inside the insert flush therewith.
  • the outer surfaces of the second layer and the insert are situated on the same plane, and the insert and the decorative element are free of the second layer on the outside and are secured in the plastic sheet by the adhesive layer.
  • the foil layer length and width are selected so as to be less than those of the plastic sheet.
  • the foil layer in this technical solution may be made of a noble (precious) metal.
  • the decorative element may be made of a natural, or precious, or semi-precious stone.
  • This device has no means for data inputting to and reading from the pay card remotely (i.e., NFC). Moreover, the use of the first and the second laminating layers impairs the visual appearance of the foil layer, if the latter is made of a noble metal.
  • the closest solution is a contactless chip card comprising a flat card, primarily of rectangular shape, a IC chip, a dielectric substrate with the IC chip installed thereon, an antenna made of an electric conductor that is arranged along the periphery of the flat card plane and connected by contact conductors to the IC chip.
  • JP, A, 11-219420 JP, A, 11-219420
  • the device represents a laminated plastic card (“smart-card”), wherein the antenna is made in the form of a multiturn coil.
  • a microprocessor having memory may be used as the IC chip. Due to the availability of an antenna, these types of devices may communicate with a remote reading device. The antenna not only performs the function of a communication means, but also may be used for obtaining energy necessary for powering the electronic chip.
  • chip cards are “faceless” per se, since the feature elements relating to a pay system and an issuing bank, protection and personalization are introduced directly into the IC memory, and, if such features become known to a stranger, a malefactor can use such cards easily. Furthermore, such plastic cards are not sufficiently reliable, their service life is limited due to the possibility of mechanical damage.
  • This invention is based on the task of providing a contactless chip card that ensures a longer service life, has improved performance and reliability due to the use of noble metals subject to regulating or minimizing their consumption, as well as that is personalized due to a variety of appearances, and, thus, has improved performance, being a card for servicing VIP-clients.
